5 kho kev kho rau hluav taws xob soldering hlau
1. Rau cov khoom siv hluav taws xob tshiab zoo tib yam, kev tshuaj xyuas tsim nyog yuav tsum tau ua. Ua ntej, xyuas seb qhov kho cov ntsia hlau puas xoob. Qhov thib ob, saib seb cov hlua hluav taws xob puas muaj qhov tawg, raug tooj liab, lossis puas. Tom qab ntawd, siv lub multimeter los ntsuas seb puas muaj qhov luv luv lossis qhib Circuit Court ntawm ob qho kawg ntawm lub ntsaws. Thaum kawg, siv lub multimeter hauv X10K iav, nrog ib txhais ko taw kov lub taub hau hluav taws xob thiab lwm yam ko taw kov cov hluav taws xob soldering hlau ntsaws tib lub sijhawm. Lub pointer ntawm lub multimeter yuav tsum tsis txhob txav mus. Tsuas yog tom qab cov kauj ruam saum toj no tuaj yeem siv tau
Thaum siv lub taub hau tshiab soldering hlau thawj zaug, cov txheej txheem hauv qab no yuav tsum tau siv los txhim kho nws txoj kev siv thiab txuas ntxiv nws lub neej kev pab. Yog hais tias nws yog ib tug tsis tu ncua soldering hlau, lub taub hau hlau soldering yuav tsum tau xub muab tso rau hauv lub qhov cub cua sov lub qhov thiab kho screws ntawm lub soldering hlau taub hau yuav tsum tau nruj nreem ntsaws rau hauv lub hwj chim thiab tso lub soldering hlau rau saum lub rosin. Raws li qhov kub nce siab, rosin melts, npog lub hau ntawm cov hlau soldering nrog ib txheej ntawm rosin tov. Tom qab ntawd, muab cov rosin soldering hlau rau ntawm qhov kawg ntawm cov hlau soldering kom txog thaum lub solder melts. Thaum kawg, sib npaug ntawm cov chrome taub ntawm cov hlau soldering nrog ib txheej ntawm tin. Cov hlau nplaum tuaj yeem muab tso rau hauv ib txwm siv
Thaum siv, qhov chaw ua haujlwm ntawm lub tshuab hluav taws xob lub taub hau yog qhov hnyav heev, nrog rau qhov kub thiab txias thiab yooj yim oxidation. Lub flux yog corrosive thiab yooj yim rau corrode, thiab hardness ntawm solder yog siab, uas tuaj yeem yooj yim ua rau hnav thiab tsim kua muag. Cov teeb meem tseem ceeb ntawm lub taub hau hlau yog feem ntau tsis noj tin (oxidation) thiab kev puas tsuaj. Rau cov taub hau hlau ua los ntawm cov hlau tooj liab, cov oxide txheej tuaj yeem raug tshem tawm nrog cov ntaub ntawv sib xyaw lossis cov taub hau hlau tuaj yeem txiav rau qhov xav tau. Nco ntsoov tias cov hlau soldering yuav tsum tsis txhob txiav tawm thiab txias. Tom qab ua tiav, kev ua haujlwm yuav tsum tau ua raws li cov khoom 1.3.2. Rau cov taub hau hlau ua los ntawm cov hlau, yog tias lawv oxidize, lawv tuaj yeem rov ua dua rau ntawm daim txhuam cev ntub dej thaum ntxiv rosin soldering hlau kom txog thaum lawv tau hluav taws xob. So tawm cov oxide txheej thiab rov coated saum npoo ntawm lub taub hau ntawm lub taub hau nrog ib txheej ntawm solder. Rau cov taub hau hlau uas twb tau tawg thiab puas lawm, lawv yuav tsum tau hloov
4 hluav taws xob soldering hlau yog cov khoom siv hluav taws xob uas, zoo li lwm yam khoom siv hluav taws xob, ntshai dej thiab ya raws. Yog li ntawd, thaum siv cov ntaub ntawv PDF los tsim ib qho kev sim version ntawm "pdfFactory Pro" www.fineprint.cn lossis thaum tsis siv, ceev faj tsis txhob khaws cia rau hauv qhov chaw ntub dej lossis qhov chaw ntub dej. Ntawm qhov tod tes, nws tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm hluav taws xob soldering hlau, thiab ntawm qhov tod tes, nws yog los xyuas kom muaj kev nyab xeeb, vim dej los yog noo noo tuaj yeem ua rau txo qis hauv rwb thaiv tsev ntawm hluav taws xob soldering hlau, ua rau hluav taws xob poob siab.
Nyob rau hauv cov txheej txheem ntawm kev siv hluav taws xob soldering hlau, peb tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm lub taub hau soldering thiab txhim kho vuam zoo los ntawm kev kho cov hlau soldering. Cov txheej txheem tshwj xeeb yog raws li hauv qab no: yog tias qhov kub thiab txias dhau lawm, qhov tshwm sim yog tias nws vaporizes tam sim ntawd thaum nws los rau hauv kev sib cuag nrog rosin, thiab cov tin soldering hloov golden xim (oxidized) tam sim ntawd thaum nws los rau hauv kev sib cuag nrog rosin. Tom qab ntawd, lub taub hau hlau soldering tuaj yeem txav tawm ntawm cov tub ntxhais cua sov me ntsis. Yog tias qhov kub thiab txias dhau lawm, nws yuav vaporize maj mam thaum nws los rau hauv kev sib cuag nrog rosin, thiab cov hlau tsis tuaj yeem yaj tam sim ntawd thaum nws los rau hauv kev sib cuag nrog cov hlau soldering. Nws raug nquahu kom txav me ntsis mus rau hauv cov tub ntxhais cua sov ntawm lub taub hau ntawm lub taub hau kom txog thaum nws yog soldered, thiab nws yuav yaj tam sim ntawd. Hauv lub sijhawm luv luv ({{0}} vib nas this), nws yuav tsis oxidize. Nco ntsoov tias cov hlau nplaum ntawm 30W hluav taws xob soldering hlau yog qhov zoo. Qhov ntev ntawm lub taub hau sab laug hauv cov tub ntxhais cua sov yuav tsum tsis pub tsawg tshaj 1.5CM. Qhov ntev ntawm cov hlau nplaum sab laug hauv cov tub ntxhais cua sov yuav tsum tsis pub tsawg dua 2.0CM, txwv tsis pub nws yuav ua rau lub neej ua haujlwm luv ntawm cov tub ntxhais cua sov.
